VENTILATOR FOR SHIPS, BOATS, 81.0.

Specification of Letters Patent.

Patented July 3, 1906.

Application filed September 1,1905- Serial No. 276,682.

To all whom it may concern.-

Be it known that I, EUGENE KoLBAssmFF,

a subject of the Emperor of Russia, and a resident of St. Petersburg, Russia, (my postofiice address being Wassiljewsky Ostroff, 28 Sredny Prospect, St. Petersburg:) have invented certain new and useful Improvements in or Relating to Ventilators for Ships, Boats, or the Like, of which the following is a specification.

-'- Practice has proved the difiiculty of supplying motor and other boats with air When the sea is rough. Thus it has been found necessary in motor-boats on bad weather arising for the occupants to shut themselves up in a water-tight manner and to stop the engines and to let the boat drift at the mercy of wind and currents. It is obvious, therefore, that boats of this kind should be provided with a ventilatin means enabling air to be taken in when the boat is on the surface, whereas at the moment when the boat is covered by a wave the device must'automatically close, so as not to ship water. In the event of water getting into the interior of this ventilating device it must be immediately removed therefrom. A convenient form of such a device would be one depending for its action upon centrifugal forcethat is, it would be capable of expelling water bycentrifugal action, while the air, having a much smaller specific gravity than water, would be drawn into the interior of the boat by the action of the partial vacuum or depression produced therein either directly by the engines or by special pumps or fans.

This invention relates to such a ventilating device and is illustrated in the accompanying drawings, in which- Figure 1 is a side elevation of the said fan, one-half being in vertical section, Fig. 2 being a horizontal section on line I I of Fig. 1, and Fig, 3 a plan and elevation of the fan-spindle.

The ventilator is constituted by two disks A B, between which are arranged a number of radial tubes D of any desired cross-section. These tubes, connected together, are mounted on a hollow spindle F, rotating in a stuffingbox 0, provided in the deck and driven by an electric or other motor. When a partial vacuum or depression begins to be formed in the interior of the boat, the air, being only slightly affected by the centrifugal action of the ventilator, cannot resist the action of the said depression and is consequently drawn toward the center of the ventilator and enters through the hollow spindle into the interior of the boat. In the event of water penetrating into the hollow tubes D it is immediately expelled by centrifugal force. The air as well as exhaust-gases from the oil-engines are expelled outward by any ordinary device.

The parts described are of great importance for the working of the ventilator, but there are also other parts of secondary importance. Thus at the outer end of each tube D a valve a may be arranged which opens more or less .under the action of the centrifugal force in order to admit surrounding air into the interior of the boat. The valve a is normally held open by a helical spring 1), surrounding the guiding-spindle 0, along which the valve can slide with a small amount of friction and one end of which is secured to a spider d, the other end passing through another spider e. A wave on striking the ventilator first strikes the valve or and instantaneously closes it. It will thus be seen that the object of the valves (1 is to prevent water from getting into the interior of the ventilator. They are therefore, as just stated, only of secondary importance and improve the Working of the device.

It is obvious that the diameter of the disks of the fan, the number of tubes, and their cross-section depend on the volume of air which the fan would have to admit. The tubes could be curved like vanes of a turbine, in which case the ventilator will work in a similar manner to a turbine, pumping air and expelling any water which might enter. If for any reason it were necessary to stop the supply of air, it would be suflicient to turn through a certain angle a sleeve E, surrounding the hollow spindle F of the ventilator in order to cover the inlet-openings with which the said spindle is provided.

I claim as my invention- 1. Ventilator for ships, boats and the like comprising disks, tubes arranged between said disks, a rotatable hollow spindle carrying said tubes and having openings to communicate with the interior of the ship.

2. Ventilator for ships, boats and the like comprising two disks having a space between them, tubes arranged in the space between said disks and a rotatablymounted hollow spindle carrying said tubes and having 0 eniI1l1gS to communicate with the interior 0 the s 1 3. Ventilator for ships, boats and the like comprising disks separated from each other, tubes located between said disks, a hollow spindle carrying said tubes and having openings to communicate with the interior of the ship and means arranged to close said. open lngs.

4. Ventilator for ships, boats and the like comprising two disks, tubes arranged between said disks, a hollow spindle carrying said tubes and having openings to communicate with the interior of the boat and a sleeve mounted on said spindle and adapted to close said openings.

5. Ventilator for ships, boats and the like comprising disks, tubes located between said disks, a hollow spindle carrying said tubes and having means to communicate with the interior of the ship, and means in combination with the said tubes adapted to close the same.

6 Ventilator for ships, boats and the like having two disks separated from each other, tubes arranged between the said disks, a hollow spindle carrying said tubes and provided with means to communicate with the interior of the ship, valves in combination with said tubes adapted to close the tubes and a spring normally holding the said valves open.

7. Ventilator for ships, boats and the like having disks with a space between them, tubes located in the said space, means, as valves, in combination with said tubes adapted to close the same, means for normally holding the valves open, a hollow spindle carrying the said tubes and having openings to communicate with the interior of the ship and means adapted to close said openings at will.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.

EUGENE KOLBASSIEFF.
